Something as an easy as a strength surge may not it seems to be ~ detrimental—in fact it may go unnoticed until devices fails. At the other end of the spectrum, blackouts can cause entire systems to instantly go dark. While power anomalies room inevitable, their effects should not impact your systems, if the suitable steps space taken to protect them.

You are watching: Which of the following protects your computer from brownouts or sags?

Surges/Spikes (voltage rise from lightning, etc.) can damages equipment incrementally or catastrophically

Surges and spikes room short-term voltage increases. They are frequently caused by lightning strikes, strength outages, short circuits or malfunctions brought about by power energy companies. They reason data corruption, catastrophic and costly tools damage and incremental damage that degrades equipment performance and also shortens its beneficial lifespan.

Common causes of surges/spikes:

Utility firm load shiftingMiswired electric systemsLightning strikes

Problems caused by surges/spikes:

System lockupsIncremental or catastrophic devices damageLost productivity
*

Electrical noise deserve to confuse device logic and also damage digital components, leading to random server lockups and premature board failure.

Line noise describes distortion top top AC, telephone/DSL, network or coaxial lines caused by Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). Line noise is unavoidable and also will show up on every signal at some point, despite it is not always detrimental, or even noticeable. It causes incremental electronic circuit damage, data corruption, audio/video quality problems and confusion between system components. Line noise produced by electronic devices varies greatly and can be produced by power disturbances native a variety of sources, both natural and man-made.

Common reasons of heat noise:

Radio transmissionsHigh voltage strength linesSevere weatherFluorescent lights

Problems caused by line noise:

System lockupsAudio staticVideo "snow"Slow electronic destruction

A brownout is a voltage deficiency the occurs once the need for power exceeds strength availability. Brownouts generally last for a couple of minutes, but can critical up to several hours, as opposed to short-lived fluctuations like surges or spikes. They are caused by the disruption the an electric grid and also may be imposed by energy companies when there is an overwhelming need for power. Brownouts, more common than blackouts, cause equipment failures, incremental damage, decreased equipment stability and data loss.

Common causes of brownouts/undervoltages/sags:

Inadequate utility serviceHeavy power attract in area/facilityPoor electrical circuit design

Problems resulted in by brownouts/undervoltages/sags:

Active data lossSystem lockupsLost productivitySlow electronic destruction
*

Swells space basically opposing of a brownout: rather of a voltage deficiency, or sag, a puffy is a voltage boost for a lengthy duration (seconds to a minute), as opposed come a brief increase, choose a surge/spike. A swell is caused when the power being detailed outweighs the power accepted by linked equipment, result in boost in voltage. Lot like sags, degradation may no be noticeable until it"s also late, bring about lost data and also damaged equipment.

Common causes of swells/overvoltages:

Sudden/large load reductionsOversupply of strength from utility sourceFault top top a 3-phase system

Problems resulted in by swells/overvoltages:

Slow electronic degradationFlickering lightsOverheating and also stress on tools
*

A blackout, or power outage, is a complete loss of utility power, even if it is short- or long-term. Blackouts cause reduced productivity, lost revenue, device crashes and also data loss. Unplanned outages may take place as aging electrical grids and building circuits are overwhelmed by high demand. Blackouts are specifically dangerous in ~ sites where security or life support rely on power, such together hospitals, therapy centers and also power plants.

Common reasons of blackouts/power outages:

Utility company failureAccidental AC line disconnectionTripped circuit breakersSevere weather

Problems resulted in by blackouts/power outages:

Data lossSystem downtimeLost productivityLost revenue
The Solution

Affordable solutions safeguard equipment, data and also productivity versus the risks of power problems. Services are easily accessible for any type of size application, from house to companies business, and also offer varying levels that protection, ranging from protection against common risks like surges and also line noise, to the most finish protection available against every hazards.


The chart listed below illustrates which solutions fit certain needs:
Surge/Spike Line Noise Brownout Swell Blackout
Surge Protector Good Good
Standby UPS Good Good Good Good Good
Line-Interactive UPS Good Good Better Better Good
On-Line UPS Best Best Best Best Best

Surge Protectors

Protect every computers and also electronics

Surge protectors administer heavy-duty surge/spike protection and line noise filtration. Premium rise protectors incorporate an ext and dramatically stronger security components, and isolated filter banks that get rid of interference in between devices plugged right into the exact same surge protector. Choose models include data line security (telephone/DSL, coaxial and/or Ethernet).


Standby UPS Systems

Protect PCs and workstations

Standby UPS systems administer surge/spike/line noise protection favor surge protectors, and they add battery backup to keep linked equipment operating without interruption during blackouts. They additionally provide minimal brownout security by convert to battery power to exactly undervoltages. Select models include data line protection and also communication harbor that enable automatic shutdown of associated computers during extended blackouts.


Line-Interactive UPS Systems

Protect workstations, servers, data centers and network equipment

In enhancement to the protection features readily available by standby UPS systems, line-interactive UPS systems add automatic voltage regulation (AVR). AVR permits the UPS device to change voltage to safe levels during brownouts without switching to battery power, to reduce battery wear and also preserving charge levels because that blackout protection.


On-Line UPS Systems

Protect servers, VoIP systems and other mission-critical equipment

On-Line UPS systems market the best protection obtainable against all strength problems. True on-line procedure with constant AC-to-DC-to-AC double conversion totally isolates electronics from power problems. Precision-regulated output power with pure sine waveform assures maximum security for linked equipment.
